Coronary occlusion and rupture of the aortic root or annulus remain two major concerns of transcatheter aortic valve implantation technique. Despite their relatively low frequency they raised the interest of the scientific community as they carry an extremely poor prognosis. Prosthesis type and size selection is part of the patient selection process that allows the operator to prevent these complications. In this article, the techniques used either during pre-TAVI screening or during the procedure itself to avoid coronary occlusion and aortic rupture will be discussed.
冠状动脉阻塞以及主动脉根部或瓣环破裂仍然是经导管主动脉瓣植入技术的两个主要问题。尽管它们的发生率相对较低,但由于预后极差,引起了科学界的关注。假体类型和尺寸的选择是患者选择过程的一部分,这使操作者能够预防这些并发症。在本文中,将讨论在经导管主动脉瓣植入术前筛查或手术过程中用于避免冠状动脉阻塞和主动脉破裂的技术。
